^ ille^ it 'known that ll, NAroiinoN @Aroma citizcn'ot the United iStates', residing at Nashua, in the county of Hi]lsboroughaiul State'y of @Neiva Hampshire, have invented new: audcusefull `'Iioprovcineuts in Loom- Shuttle-Tln-'ead Guides, ot' which. the iollowing-.is a specilication. 41`

My present invention j has '-.reference to loom shuttlesf,y andhas for its object to'sinipliliy-and' improve the threadguide 'for such shuttles. i' f' j A: turther object :is to` produce a thread guide for loom .shuttles otra construction whereby the shuttle may be readily threaded by hand' and which includes a. Vtriction de` vice oi telt -orilannelifor securing the required tension upon the thread. s

i il, 'stil-l' further object `is the. production of a thread." guidci for shuttles formed from a relatively short metal strip secured in one side of the throat portion of the shuttle, inward of the vertical and lateral slots in the nose thereof that provide guide-s in the threading of the shuttle, and which strip has its lower portion rounded upon itself to provide a substantially elliptical `thread guide, the inner wall of which being slightly spaced from the strip proper, andthe end wall of which being slightly spaced from the initial bend in the said rounded portion so that the thread may be readily slipped between the side of the strip and the said inner rounded portion of the guide,the outer rounded wall of the guide being notched to provide a pocket for a friction strip of telt or flannel.

To the attainment of the foregoing, reference is to be had to the drawing which accompanies and which forms part ot this application.

In the drawing :m

Figure l is a top plan view of one end of a loom shuttle illustrating the application ot' the improvement therein.

Figure 2 1s a side elevation of the end i ot' the shuttle provided with the improvement.

Figure 3 is a top plan view of the said end of the shuttle with parts broken away and parts in section, the improvement being also in section.

yAnooiiisirufr'rLn-{rrranan GUIDE.

e, i924, semaine. celata The `shuttle is ot the ordinary construction and is indicated by the numeral l. rI`he shuttle, at one of the nose ends 2 thereof, is formed with a central depression which I will terni `a throatvand which is indicated by the numeral 3. The vertical angularly arranged'tl'iread guide slot through -thenosc .is indicated by the numeral #l and the horizontal slot by the numeral The horizont-al slot communicates with a depression in. one side ot the nose, and in this `depression there is secured an outer thread guide of the usual construction.

My.in'iprovefdv thread guide is formed from a: relatively .short strip `of suitable metal,

having oneend formed with an angle por c tion or ear G seated in a suitable depression at one side of whatl I have termed the throat in thenose l, and secured thereto by means 7. The strip, troni its angle end or ear` is in contacting engagement with one of the side walls provided by the throat 3. This straight portion of the strip is indicated by the numeral 8. The straight portion 8 of they strip is rounded outwardly upon itself5 as at 9, and is troni thence coiled to provide a substantially elliptical guide eye l0. The inner wall oi the guide eye, that is the Wall next to the straight portion S of the strip, is spaced therefrom, and the end ot the elliptical guide eye terminates approximate ly in a line with the longitudinal center ot the rounded portion l), but is slightly spacedl therefrom. This permits ot vthe thread being readily passed into the v eye. The outer side ot the eye is Aformed with a slot ll. This slot provides a pocket for the ends of a fric-tional elementin the nature of a strip `of felt or Hannel, indicated by the numeral l2.

Preferably I secure in the lower wall ot the throat, in a line with the outer side of the guide eye l0 a cross sectionally rounded pin 13, and this pin is disposed in a line with the outer guide eye 14 of the shuttle.

It is believed that the foregoing description, when taken in connection with` the drawing, will fully set forth the construcf one of the side walls of the throat in the nose portion of the shuttle, and having its lower portion rounded and continued in elliptical formation against the bottom and opposite side wall of the throat, the inner wall of the elliptical portion of the guide being spaced from the straight side thereof and the terminal edge thereof being disposed approximately in a line with the longitudi nal center of the first mentioned rounded portion but slightly spaced therefrom.

2. A thread guide for loom shuttles formed `from a relatively short strip of metal having a straight side to be arranged against one of the side walls of the throat in the nose portion of the shuttle, and having its lower portion rounded and continued in elliptical formation against the bottom and opposite side wall of the throat, the inner wall of the elliptical portion of the guide being spaced from the straight side thereof and the terminal edge thereof being disposed approximately in a line with the longitudinal center of the first mentioned rounded portion but slightly spaced therefrom, and the outer side wall of the said elliptical portion being notched to provide a pocket, and a fabric frictional agent in said pocket and entering the bore of the guide.

3. A thread guide for loom shuttles formed from a relatively short strip ofV metal having a straight side to be arranged against one of the side Walls of the throat in the nose portion of the shuttle, and having its lower portion rounded and continued in elliptical formation against the bottom and opposite side wall of the throat, the inner wall of the elliptical portion of the guide being spaced from the straight side thereof and the terminal edge thereof being disposed approximately in a line With the longitudinal c enter of the irst mentioned rounded portion but slightly spaced there from, and a frictional fabric in the guide.

ai. A thread guide for loom shuttles formed from a relatively short strip of metal having one end bent to provide an ear for the reception of a securing element, the opposite end of the strip being rounded elliptically upon itself, the inner wall of the elliptical portion being slightly spaced from the straight portion of the strip, and the terminal of the said elliptical portion being disposed approximately in a line with the longitudinal center of the initial rounded portion.

In testimony whereof I affix my signature.
